  abstract = {{A}im{P}anbiogeographers suggest that the biome in {N}ew {C}aledonia is of vicariant origin, dating from the {C}retaceous - rather than being the result of repeated dispersal since c. 37{M}a, when the area is postulated to have re-emerged after c. 15million years of submergence. {D}istributions of the plant family {S}apotaceae were used as a model system to test this, and to elucidate the probabilities of ancestral areas, all phrased in six hypotheses. {L}ocation{A}ustralasia and the {P}acific. {M}ethods{W}e used a recently published dataset with extensive sampling (168 terminals) from the subfamily {C}hrysophylloideae and three nuclear ribosomal {DNA} markers. {P}hylogenetic divergence times and ancestral areas were estimated in a {B}ayesian framework using beast, a relaxed clock method, and with fossil calibration points. {A}rea transition probabilities were modelled using a reversible rate matrix, assigning equal prior probability to each transition between two areas. {R}esults{O}ur analyses suggest that {S}apotaceae arrived and diversified in {N}ew {C}aledonia nine times during the period 4.2-33.1{M}a. {A}ll crown-node radiations occurred in the {M}iocene or {P}liocene, with stem splits reaching back into the {O}ligocene. {A}ustralia and {N}ew {G}uinea are the most likely source areas for {S}apotaceae in {N}ew {C}aledonia, but this archipelago has never acted as a stepping stone for {S}apotaceae to disperse into the {P}acific. {M}ain conclusions{R}epeated dispersal is the only mechanism able to explain the range expansion of {S}apotaceae into {N}ew {C}aledonia. {T}he family has successfully colonized the main island nine times since its re-emergence in the {E}ocene. {W}e reject the panbiogeographical hypotheses that representatives of {S}apotaceae in {N}ew {C}aledonia originated in the {C}retaceous, differentiated due to vicariance, and were of {P}acific origin. {W}e therefore argue that {N}ew {C}aledonia is an old {D}arwinian island. {T}he {P}acific has been colonized repeatedly and terminal lineages are never older than the islands they inhabit (except for {H}awaii). {C}hrysophylloideae extended across {W}allace's {L}ine into {S}outheast {A}sia around 20{M}a, when the {A}ustralian continent came into juxtaposition with {E}urasia.},
